AP7370-50WW-7 Equivalent & Substitute Parts

Part Overview

The AP7370-50WW-7 is a linear voltage regulator IC from Diodes Incorporated, classified as a Power Management (PMIC) component. This device delivers a fixed 5V output at 300mA maximum current in a surface-mount SOT-25 package. The regulator is designed for applications requiring stable positive voltage regulation with integrated protection features including over-current, over-temperature, reverse-current, and short-circuit protection. The part maintains Active product status and is RoHS3 compliant. Equivalent substitute parts are identified based on matching electrical specifications and mechanical compatibility within the AP7370 series.

Substitute Part Grouping Explanation

Substitute parts for the AP7370-50WW-7 are identified as parametric equivalents within the AP7370 series. Substitution is valid when the following criteria are met:

• Output voltage configuration: Positive, Fixed at 5V
• Output current rating: 300mA
• Maximum input voltage: 18V
• Dropout voltage: 0.55V @ 100mA
• Quiescent current: 2.5 µA
• Package type: SOT-25 (SC-74A, SOT-753)
• Operating temperature range: -40°C ~ 125°C (TJ)
• Protection features: Over Current, Over Temperature, Reverse Current, Short Circuit
• Compliance: RoHS3 Compliant, REACH Unaffected
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitutes (AP7370-50W5-7 and AP7370-50WR-7) share identical electrical and mechanical specifications with the main part number, differing only in packaging configuration (tape & reel variants). All three parts are manufactured by Diodes Incorporated and maintain Active product status.

Frequently Asked Questions (FAQ)

Q: Can AP7370-50W5-7 and AP7370-50WR-7 be used as direct replacements for AP7370-50WW-7?

A: Yes. All three parts share identical electrical specifications (5V output, 300mA current, 18V maximum input, 0.55V dropout voltage) and mechanical compatibility (SOT-25 package). The differences in part number suffixes reflect packaging variants only.

Q: What determines substitution eligibility for the AP7370-50WW-7?

A: Substitution is valid when the replacement part maintains: fixed 5V output voltage, 300mA output current rating, 18V maximum input voltage, 0.55V dropout voltage at 100mA, SOT-25 package configuration, and identical protection features (over-current, over-temperature, reverse-current, short-circuit).

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts are RoHS3 compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Compliance status is identical across all substitute options.

Q: What is the operating temperature range for these regulators?

A: The operating temperature range is -40°C to 125°C (junction temperature). This specification is consistent across all three part numbers.

Q: How do the quiescent current specifications compare?

A: All three parts have identical quiescent current specifications of 2.5 µA, ensuring equivalent power consumption characteristics in standby or low-load conditions.
